Type material: Holotype: ♂, Estación Biológica de Chamela (19°29’N, 105°02’W), Chamela , Jalisco , Mexico, 25 March 2000, F. Alvarez, E. Gonzáles, O. Delgado, J.L. Castelo, E. Lira, O. Francke & C. Durán leg. ( CNAN 3370). Paratypes: 1♀, 1 juv., same data as holotype ( CNAN 3370); 2♀, same locality as holotype, September 1988, W. Eberhard leg. ( MCZ 69120; 48843); 1♂, same locality as holotype, 6 September 1981, M.L. Jiménez leg. ( CNAN 3350).

FIGURES 27−30. Curicaberis chamela sp. nov. 27− 28 male, left palp (27 ventral, 28 retrolateral); 29− 30 female (29 epigyne, ventral view, 30 vulva, dorsal view). C = conductor; CD = copulatory duct; CO = copulatory opening; dRTA = dorsal branch of RTA; E = embolus; FD = fertilization duct; LL = lateral lobes; MS = median septum; SP = spermathecae; ST = subtegulum; vRTA1 = projection 1 of ventral branch of RTA; vRTA2 = projection 2 of ventral branch of RTA. Scale lines: 1 mm.

Etymology. The specific name is a noun in apposition and refers to the type locality.

Diagnosis. Males of C. chamela sp. nov. are distinguished from those of the other species of the genus by the palp with vRTA1 anvil-shaped in ventral view (Fig. 27) and vRTA2 bifid, roughly rectangular in retrolateral view, with one large and rounded point, the other small and slightly more pointed (Fig. 28). Females resemble those of C. chamela sp. nov., C. minax comb. nov., C. abnormis comb. nov. and C. sanpedrito sp. nov. by the epigyne with very conspicuous round and large copulatory openings (Figs 29, 75, 89, Rheims 2010c: 534, fig. 11). They are distinguished from these species by the median septum rebordered throughout its entire width and by the slender lateral lobes, curved towards each other posteriorly (Fig. 29).

Description. Male (holotype): Prosoma orange with anterior lateral margins brown, slightly darker along fovea and with brown marks on cephalic region. Chelicerae orange with longitudinal brown stripe. Pedipalps orange. Legs orange, mottled with pale gray spots. Labium and endites pale orange, distally cream colored. Sternum pale orange with slightly darker margins. Opisthosoma cream colored dorsally mottled with brown spots laterally, with brown marks around cardiac impression and four median brown chevrons on posterior half, ventrally mottled with brown spots. Total length 10.3. Prosoma: 4.9 long, 4.9 wide. Opisthosoma: 5.2 long, 4.0 wide. Eyes: diameters: 0.36, 0.32, 0.26, 0.32; interdistances: 0.20, 0.10, 0.40, 0.44, 0.34, 0.24. Legs (2143): I: 29.5 (7.9, 2.8, 8.0, 8.4, 2.4); II: 31.8 (8.6, 3.0, 8.7, 9.0, 2.5); III: 21.5 (6.4, 2.5, 5.5, 5.5, 1.6); IV: 25.0 (7.4, 2.4, 6.7, 6.8, 1.7). Palp: dRTA short. Subtegulum visible at 10 o’clock position. Embolus long, sinuous, arising medially from tegulum. Conductor widened at tip (Figs 27−28).

Female (CNAN 3370): Coloration as in male. Total length 12.3. Prosoma: 5.2 long, 4.4 wide. Opisthosoma: 5.2 long, 5.0 wide. Eyes: diameters: 0.36, 0.36, 0.28, 0.30; interdistances: 0.30, 0.20, 0.56, 0.60, 0.38, 0.36. Legs (2143): I: 25.3 (7.0, 3.0, 6.3, 7.0, 2.0); II: 26.8 (7.7, 3.2, 6.7, 7.3, 1.9); III: 18.1 (5.7, 2.4, 4.5, 4.2, 1.3); IV: 21.1 (6.6, 2.5, 4.9, 5.6, 1.5). Epigyne: epigynal field semi-circled, wider than long. Posterior margin of median septum not surpassing the epigastric furrow (Fig. 29). Vulva: copulatory ducts longer than spermathecae length. Spermathecae small, curving away from each other. Glandular projection not visible in dorsal view, probably hidden behind copulatory ducts. Basal part of fertilization ducts almost one-third copulatory duct width with one coil, distal part laterad (Fig. 30).

Variation. Females (n = 4): total length 12.3–13.2; prosoma length 4.6–5.3; femur I length 6.2–7.0. Distribution. Known from the state of Jalisco , Mexico (Map 1).
